Send Big Russ a PM on here, im sure he can sort this for you.

Does it still work the locks?
Have you still got the transponder chip ?
What happened ?

hi to all
the fob does not open or close the doors the transponder is there and the key starts the engine when you press the fob to lock the doors the light comes on but does not lock the doors when you press the fob to open the doors the light does not come on and does not open the doors the key locks the drivers door but not lock the other doors

Puzzled as to why you want a new transponder :shrug: It works and replacing the transponder isn't straightforward, requires specialised equipment which only a handful of the traders have.

The remote PCB is another matter, as long as you have access to either a T4 or somebody who knows what they're doing with TOAF you can enter replacement PCB serial number.

hi to add
the transponder is working i think the circuit board is at at fault the switches that open and close the doors

You can buy a secondhand key and transfer the PCB to your key and program it using Marinabrian's instructions here.

Alternatively, new microswitches are available -

however, you'll need fine soldering skills to replace them.

Have you tried a new key battery David?
